STAC5 Ethernet Hardware Manual
Connecting the Drive to Your PC using Ethernet
This process requires three steps:
• Physically connect the drive to your network (or directly to the PC)
• Set the drive's IP address
• Set the appropriate networking properties on your PC.
Addresses, Subnets, and Ports
Every device on an Ethernet network must have a unique IP address. In order for two devices to
communicate with each other, they must both be connected to the network and they must have IP
addresses that are on the same subnet. A subnet is a logical division of a larger network. Mem-
bers of one subnet are generally not able to communicate with members of another unless they
are connected through special network equipment (e.g. router). Subnets are defined by the choic-
es of IP addresses and subnet masks.
If you want to know the IP address and subnet mask of your PC, select Start...All Programs...Ac-
cessories...Command Prompt. Then type "ipconfig" and press Enter. You should see something
like this:
If your PC's subnet mask is set to 255.255.255.0, a common setting known as a Class C subnet
mask, then your machine can only talk to another network device whose IP address matches
yours in the first three octets. (The numbers between the dots in an IP address are called octets.)
For example, if your PC is on a Class C subnet and has an
IP address of 192.168.0.20, it can talk to a device at
192.168.0.40, but not one at 192.168.1.40. If you change
your subnet mask to 255.255.0.0 (Class B) you can talk to
any device whose first two octets match yours. Be sure to
ask your system administrator before doing this. You
network may be segmented for a reason.
Your drive includes a 16 position rotary switch for setting
its IP address. The factory default address for each switch
setting is shown in the table to the right.
Settings 1 through E can be changed using the ST
Configurator software Setting 0 is always "10.10.10.10", the
universal recovery address. If someone were to change the
other settings and not write it down or tell anyone then you
will not be able to communicate with your drive. The only
way to "recover" it is to use the universal recovery address.
Setting F is "DHCP", which commands the drive to get an IP address from a DHCP server on the
network. The IP address automatically assigned by the DHCP server may be "dynamic" or "static"
